Preheat your oven to 350 and spray your mini muffin tin with cooking spray
To a large mixing bowl add your bananas and mash well
Add in remaining wet ingredients (yogurt, oil/butter, honey, vanilla, and egg) and mix until well combined
Add in salt, baking powder, baking soda, and flour, and mix just until everything is incorporated (do not overmix)
Add to your mini muffin tin - I filled to the top, but you can do less, just adjust the baking time
Cook for 15 minutes (less time if less filled)
Cool slightly, then remove and cook completely on a cooling rack
Enjoy!
